So , it is definitely different from other amb - ab . three aspects have been studied theoretically in this paper which were based on an analysis of a compliant multleaf journal self - acting air bearing , which are as follows : ( 1 ) a set of theoretical analysis method which include the development of . physical and mathematical model , the solution of governing equations and the prediction of static and dynamic performance of the foil gas bearing is proposed . the above theoretical analysis method provides a possibility for numerical analysis 本文在分析懸臂型彈性箔片徑向動壓氣體軸承工作原理的基礎上,做了以下幾個方面的工作: ( 1 )建立了懸臂型彈性箔片徑向動壓氣體軸承的物理和數學模型,確立并求解了控制方程,得到了靜、動態性能的穩定性分析方法,為數值分析懸臂型彈性箔片徑向動壓氣體軸承奠定了基礎。

The air bearing is the most important part of an attitude control system simulator for simulating a satellite moving in the weightless circumstance . performance of a satellite attitude simulation system based on air bearing is decided by the inertia matrix and gravity disturbance torque arising from a difference between mass center and rotation center , and air bearing can be used to simulate the algorithm of on - line mass - property parameters identification on the ground . so the problem of mass - property and gravity disturbance torque identification for satellite and air bearing is studied in this thesis 氣浮臺能夠模擬衛星在軌失重條件下的姿態運動,是衛星姿態控制系統物理仿真的核心部件,其轉動慣量和質心偏移引起的重力干擾力矩等決定了基于氣浮臺的衛星姿態物理仿真系統的性能,并且利用氣浮臺可以實現衛星質量特性在線辨識算法的地面物理仿真驗證,因此本文對衛星和氣浮臺的質量特性及干擾力矩在線辨識問題進行深入研究。

Because it is impossible to adjust the air bearing absolutely balance , the difference between mass center and rotation center must lead to a notable gravity disturbance torque . in the process of identification , modeling and identification of gravity disturbance torque is considered , and an extended kalman filter is educed for identifying air bearing inertia matrix and gravity disturbance torque , and then the algorithm is validated 由于氣浮臺平衡調試方法和手段的限制,實驗過程中氣浮臺質心與轉動中心有一定的位置偏差,必將導致較大的重力干擾力矩,在辨識算法的推導過程中,重點考慮了重力干擾力矩的建模和參數辨識問題,推導了氣浮臺的轉動慣量和重力干擾力矩辨識的擴展卡爾曼濾波算法,并對算法進行了數學仿真和全物理仿真驗證。

Many international experts have done research in amb - ab , but the air bearing occupying a long axis space . the rotor ' s dynamics performance is depressed . a new type amb - ab was brought forward in this paper , the film air bearing was integration in amb 本文研究了一種新型的磁氣混合軸承結構,其特點是將箔片氣體軸承集成在磁軸承的氣隙里面,不占據軸向空間,因此與國外的研究有本質的區別。

Now we unite amb with air bearing ( amb - ab ) to overcome their shortages . it is a new technology in bearing field , it will more superior than amb and air bearing 將兩者結合在一起,利用它們各自的優點并克服對方的缺點,將是軸承領域的新技術,其性能要遠比磁軸承或箔片氣體軸承的性能優越。

Air bearing has a lot of absolute advantages when it is used in high speed bearing , low friction and low wastage , high precision bearing and special conditions 氣體軸承在高速支承,低摩擦、低功耗支承,高精密支承和特殊工況下的支承等領域內有絕對的應用優勢。

Amb and foil air bearing has its inherent shortages when it is used alone 磁軸承和箔片氣體軸承都有本身固有的不足,單獨使用都存在一些問題。
